IMPROVEMENT IN SEAMS FOR 'I IIN'A CANS.

The Schedule referred to n these Letters Patent and making part of thesame.

To all whom 'it may concern Be it known that I, CHARLES 1t, Oris, ofChicago, in the county of Cook,'and in the State of Illinois, haveinvented certain new and useful Improvements in Seams for Tin Cans;- anddo hereby declare that the ,followhig is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to t-he letters of reference marked thereon, making a part of thisspecification.

'lhenature of my invention consists in the formation of the seam, forconstructing tin cans of any desired size or shape. 4

In order to enable others skilled'in the artfto which my inventionappertains, tomake and use the saine, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure l is a perspective of a square tin can, made with my improvedseam, and

Figure 2is part end view and part cross-section of a oi' the adjoiningside, which can be donc much easier and far better than any seam now inuse.

The upper and lower edges of the sides A A are bent in the same manneras the vertical edge a.

The four edges of the top B are bent at right angles, and the t'op theninserted between the upper edges of the sides A A, and solderedtogether. The bottom of the can is attached in the sannl manner.

rlhe seams of other than square cans are ma'ie in the same manner. Theedges b b, instead of being bent at right angles with the sides, arebent at the same angles'the sides are to be in relation with each other.

For round cans, the edges are, ot' course, bent rounded.

Having thus fully described my invention,

yWhat I claim as new, and desire to secure by Letters Pz tent, is-' Aseam for tin cans, formed bybonding the edges, substantially in themanner herein shown and described.

In testimony that I claim the foregoing, I have hereunto set my hand,this 28d day of August, 1869.

seam, and the manner of joining the sides together.

'To form a square can, the sides A A are formed in the following manner:

One of the vertical edges, a, of each side, is bent over close toandparallel with the side, whilethe other Witnesses: vertical edge, b, isbent at right angles with the side. C. L. Evnn'r, lhe edge b, of oneside, is then soldered to the edge W. N. SU'ron.
